Wall Stabilization with Alternating Shoulder Adduction/Abduction

Stand with your feet slightly wider than shoulder width with knees bent and feet about afoot away from the wall. Flatten
your back against the pool wall while contracting abdominal muscles. Alternate lifting one arm out to the side and the other arm back down to your side. Keep elbows straight. (Arms do not raise above the water) (Increasing speed will increase resistance)
